F AN ATTACHMENT FOR SEWING-MACHINES.

i To all whom it may concern.-

Be it known that I, NICHOLAS W. OEASE, a

.citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Fan Attachments for Sewing- Machines, of which the following is a specification.

. s i This invention relates to new and useful I improvements in fan attachments for sewingmachines; and its primary obj ect is to provide adevice of simple construction which can be r easily connected to the arm of a sewing-machine of any make and which is so secured thereto as to prevent injury by scratching or i in any other similar manner.

A further object is to so construct the de- ;vice thatthe same maybe readily taken apart for convenience in packing.

Another object is to provide means wheret by the fanmay be adjusted back and forth within its standard, so as to bring a pulley which is secured thereto in vertical aline- 1 ment with the driving-pulley.

25. Afurther object is to provide a fan of novel r construction for use in connection with the attachment.

With these and other objects in view the invention consists in providing a base-plate which is provided at suitable intervals with threaded apertures, any one of which is adapted to receive the lower threaded end of a standard. Any one of these apertures is also adapted to receive a screw which is adapted to secure a clip to the base. This clip, as

Well as the base, is provided with soft protecting material, as felt, whereby injury to the arm to which the attachment is secured is. prevented. One of the remaining apertures within the base is adapted to receive the spool-spindle of the arm in order that l the attachment may be held securely in position. A sleeve is arranged at the upper end i of the standard and is adapted to receive a tube, said tube being locked within the sleeve by means of a setscrew. A spindle is revo- .luble within the tube and is provided at one 3 end with a pulley, while the opposite end is tion through the attachment.

detachably secured to a cylindrical hub having longitudinally-extending slots therein arranged in planes at right angles to each other. These slots are adapted to receive interlocking'fan-blades, which extend from the cylinder at right angles to each other, and the outer end of said cylinder is threaded and is adapted to project into a nut which serves to bind the slotted end of the cylinder together and also prevents the accidental removal of the fanblades. The invention also consists in the further novel construction and combination of parts, which will be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure l is a perspective view showing my fan' attachment in position upon the arm of a sewing-machine. Fig. 2 is a vertical see- Fig. 3 is an enlarged section through the hub of the fan, showing the fan-blades in position therein. Fig. 4 is a detail view of the hub detached. Fig. 5 is a similar view of a fan-blade.

Referring to the drawings by numerals of reference, 1 is the arm of a sewing-machine, having a spool-spindle 2 extending upward therefrom. This spindle is adapted to project through any one of a series of threaded perforations 3, formed within the base-plate 4 of my improved attachment. Secured to the lower surface of this plate is a pad 5, preferably wedge-shaped in side elevation and formed of any suitable material, as rubber or felt. This pad is also provided with apertures therein which are adapted to register with the apertures within the base-plate. A clip 6, formed of spring metal,.extends over the base-plate 4: and downward therefrom, the ends of said clip being bent toward each other, so as to extend under the arm 1. Downward extensions 7 are arranged at the ends of the clip, and each extension has a series of perforations 8 for the reception of suitable securing means, as a thumb-screw 9. This clip is provided upon its inner surface with a covering 10, of felt or other similar.

material, and is secured to the base-plate 4: by means of a screw 11, which is adapted to engage the walls of any one of the perforations 3. Fitted within one of these perforations is the threaded end of a standard 12, to the upper end of which is secured a sleeve 13. A set-screw 14: is arranged within this sleeve and is adapted to bind upon a tube 15, fitted within the sleeve. It will be readily seen that when the set-screw14 is turned outward this tube may be slipped longitudinally within the sleeve and after reaching the desired position may be locked by said screw.

A spindle or rod 16 is revoluble within the tube 15. 'A pulley 17 is secured at one end of this red, while the opposite end is threaded and extends into one end of the tubular hub 18 of the fan proper. This tube is slotted from one end to a point adjacent to the inner end thereof, said slots 19 intersecting and being arranged in planes at right angles to each other. Each of the slots is adapted to receive one of the sections 20 of the fan. Each of these sections, as shown in Fig. 5, forms two of the fan-blades and is constructed of a single piece of sheet metal or similar material having a longitudinally-extending slot 21 at the center thereof and extending for one-half of its length. The slots 21 within the two portions 20 of the fan extend inward from opposite edges thereof, and these slots permit the blades to interlock, as shown in Fig. 2. The blades are then slipped into the intersecting slots 19 of the hub 18 and the outer end 22 of the hub is placed into engagement with a nut 23,.which serves to bind said end together and also prevents the accidental displacement of the blades. If desired, the inner edges of the plates 20 may be recessed, as shown at 24, so as to extend for a desired distance beyond the inner ends of the slots 19 in the hub.

. The pulley 17 upon the rod 16 receives motion through a belt or cord 25 from a second pulley 26, mounted at the center of the handwheel 27 of the sewing-machine. This pulley 26 may also be employed for throwing the mechanism within the arm of the sewing-machine into or out of engagement with the op erating mechanism.

It will be seen that when the attachment is to be used upon sewing-machine arms having the spool-spindle arranged at a greater or less distance from the hand-wheel 27 it is only necessary to place the spindle 2 in the proper aperture 3 within the base-plate. Moreover, the clip 6 can be adjusted to the arm at any point thereon by simply placing the thumbbolt 9 within the proper aperture 8. The standard 12 may be placed in the desired aperture 3, and by providing the adjustable tube 15 the pulley 17 may be slid back or forth until the same arrives in vertical alinement with the pulley 26.

The fan is extremely simple in construction esi,1ee

"and durable, andthe blades may be readily detached when it is desired to pack the de vice.

By providing a wedge-shaped pad, as 5, the base-plate is held at all times in a horizontal position and, moreover, securely grips the arm upon which it rests.

In the foregoing description I have embodied the preferred form of my invention; but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of'this invention, and I therefore reserve to myself the right to make such changes as fairly fall within the scope thereof. 7
